ALL MOUTH AND
TROUSERS - "adj. British. Blustering and boastful, showing off without having
the qualities to justify it.There is a suggestion that this is a corruption of
a more logical, but rarely heard expression, 'all mouth and no trousers'. meaning
full of talk but deficient in the sexual area. A less racy version is 'all talk
and no action'. ." From the "Dictionary of Contemporary Slang" by Tony Thorne
(Pantheon Books, New York, 1990).

On White Oak Mountain in W.Va., we called
a boastful person a "blow George." In Texas, it is "all hat and no cattle."
